That is a very good point! That’s one reason their stats are so slanted towards a certain clique of white dudes: a few bloggers are posting every day/couple of days, others have posted once and then never again. It’s a fairly common thing on group blogs (I’m pretty sure The Standard would be heavily slanted toward lprent/Eddie/karol in the same way) but it does make it sound a bit silly to complain about one person who has a significant back catalogue not being a “real” blogger.
